Description

Technical Field

[0001] This utility model relates to a solar wall lamp, and more particularly to a hinged solar lamp. Background Technology

[0002] Wall lamps are auxiliary lighting and decorative lamps installed on interior walls. There are many types and styles of wall lamps, the most common being ceiling lights, color-changing wall lamps, bedside wall lamps, and mirror wall lamps. They are often installed on balconies, staircases, corridors, and bedrooms, and are suitable for use as lights left on all night. Existing wall lamps are mainly divided into conventional wall lamps that connect to a 220V power supply and new energy wall lamps that use solar power.

[0003] Conventional wall lamps have a wider range of applications and can be used both indoors and outdoors. However, new energy wall lamps, which are powered by solar energy, can only be installed on outdoor walls that are easily exposed to sunlight. Because conventional wall lamps consume a lot of electricity, their operating costs are relatively high. In contrast, new energy wall lamps generate electricity from solar power, resulting in lower electricity costs. Furthermore, unlike conventional wall lamps, they are not restricted by power cords and are more flexible in use. Therefore, the outdoor application of new energy wall lamps is gradually becoming more widespread.

[0004] Solar wall lights mainly consist of photovoltaic (PV) components and a light-emitting body. Existing solar wall lights can have separate PV components and light-emitting bodies, meaning they are independent entities connected by a power cord; or they can be an integrated structure combining the PV components and light-emitting body. Separate PV components and light-emitting bodies in solar wall lights require both to be fixed to the wall surface, making assembly and disassembly cumbersome, and they occupy a large space, making storage and transportation inconvenient. While integrated solar wall lights reduce installation space, the illumination angle of the light-emitting body cannot be flexibly adjusted, a drawback also present in separate PV wall lights, resulting in inflexible use. Furthermore, currently, both separate and integrated solar wall lights have their internal battery packs enclosed within the wall light's casing and electrically connected to the photovoltaic controller via welding. Once the battery pack is damaged or reaches the end of its lifespan, replacement is very troublesome, increasing the product's operating costs. Utility Model Content
